To (LU whom it nuty concern."

Be it known that I, THOMAS Ronennson l\'lIA.i-':sDEN, a subject of the Queen of England, and a resident of Oldham, Lancaster county, hug] and, have invented certain new and use ful Improvements in Feeding-Machines for Cotton and Fibrous Material, (patented in Great Britain, No. 10,254, May 24-, 1893,) of which the following is a specification.

The object of my invention is to arrange the feeding-machine so that the fiber shallbe well opened and delivered in regular quantities onto the feed-lattice of the machine to be fed. I employ the usual hopper, in which I mount an endless traveling lattice and an endless traveling spiked sheet. The endless lattice forming the bottom of the hopper carries the fibrous material against the spiked sheet, which may be placed in a vertical or inclined position. Above the top part of the spiked sheet I place a spiked cylinder, which is carried by a suitable iixin g, which is mounted so as to be free to swivel to a slight extent on the shaft forming the center of the stripping-cylinder. The stripping-cylinder,which is provided with blades of leather or other from .the spiked sheet, so that it may fall upon the feeder of the opener, scutcher, or carding-machine to be fed. The spiked cylinder is placed so that it can be stripped by the stripping-cylinder which strips the endless spiked sheet. By mounting the spiked roller on its movable support the distance between the teeth of the spiked cylinder and the teeth of the endless spiked sheet can be varied at pleasure, thus enabling the quantity of cotton carried forward by the endless spiked sheet to be regulated. The vertical or inclined spiked sheet carries the fibrous material out of the hopper and up to the spiked cylinder, which, revolving in a contrary direction to the endless spiked sheet, opens the fibrous material carried forward by the spiked sheet on its way to the machine to be fed. The spiked cylinder carries a small quantity of material forward, which is stripped by the strippingcylinder already referred to as having blades of leather or other material. The stripping-cylinder may also have in addition to the blades of leather indicated by the diagram Fig. 2.

spikes or pins. I also employ a strippingroller to strip lumps of material from the spiked cylinder. The spiked cylinder, which is swiveled on the center of the stripping-cylinder, is raised or lowered by the regulator -"f0r|nin g partof the machine to be fed, or it may be operated by the rising and falling of a roller resting on the cotton fed on and carried forward by the lattice of the scntcher, opener, or other machine to be fed.

In carrying out my invention I drive the vertical or inclined lattice or spiked sheet from the regulating-roller of the machine being fed. In' cases where a regulator is not used I may drive the vertical or inclined lattice or spiked sheet from the feed-roller of the machine to be fed. Instead of the spiked cylinder I sometimes use a spiked lattice, which is arranged .to be raised and lowered in the same manner and for the same purpose as the spiked cylinder.

To rend er my invention clearly understood, I will nowproceed to describe the same in detail, reference being had to the annexed two sheets of illustrative drawings.

Figure 1, Sheet 1, represents in side eleva tion the general arrangement of a feedingmachine made in accordance with my invention. The hopper or space for containing the cotton to be fed is situated between the sides A of the machine and is indicated by B. The board on forms the front of the hopper, the

traveling lattice b, moving in the direction of the arrows, forms the floor of the hopper, and the spiked sheet 0, traveling in the indicated direction, constitutes the back of the hopper. The spiked sheet 0 may be arranged either vertically or at an angle. In practice I have found it is more advantageous to have it in an inclined position. I therefore arrange the spiked sheet 0 with a forward rake or inclination, as shown in Fig. 1 and as more clearly In some cases I dispense with the hopper-front a and extend the lattice b to any required distance, the cotton or textile fiber being carried by the lattice up to the spiked sheet. This extension of the lattice I) might be inclosed on either side by fences 0. (Shown in dotted lines in Figs. 1 and 4.) This arrangement would prove convenient in certain situations where the cotton would otherwise have to be carried some distance before being placed in the hopper.

By the forward inclination or rake of the spiked sheet 0 the tendency to variation of feed existing under the different conditions of a nearly empty and a full hopper is greatly reduced.

ilhe endless traveling lattice b is supported on pulleys cl (1 and, forming the bottom of the hopper, carries the cotton or other fibrous material in the hopper against the spiked sheet 0, carried on pulleys c e, the said spiked sheet being raked orinclined forward for the indicated reasons. spiked sheet a I place a spiked cylinder h, (revolving in the direction of the arrows,) the bearings of which are carried in side levers f. The side levers f are pivoted on the shaft g of the stripping-cylinder g, which rotates in the indicated direction and which is so situated as to strip both the spiked cylinder 7b and the spiked sheet 0. The periphery of the stripping-cylinder is furnished with blades 7b, of leather, which beat and strip the fibers from the cylinder h and the spiked sheet 0, the stripped fiber passing down the chute j to the traveling feed-apron s, in connection with the scuteher or opener or other machine to which the fibrous material is being fed.

Behind the cylinder h I place a smaller spiked roller (revolving as indicated) to remove lumps or irregular portions of fiber from the cylinder h. The fiber thus removed from the cylinder h is stripped back into the hopper by a stripping-roller Z, revolving in the direction of the arrow. The aforesaid parts are driven from a shaft m, operated from the regulator.

A bevel-wheel n on the end of the shaft m operates a corresponding bevel-pinion on an upright shaft 0, and a bevel-wheel 0 on the shaft 0 drives a wheel on the end of the shaft 6 of the upper carrying-drume' of the spiked sheet 0. Thus the spiked sheets is operated.

Suitable gearing is placed between the shaft 6 and the shafts of the spiked cylinder h and the stripping-cylinder g, so that these shall be driven from the shaft c To prevent the toothed wheel of the spiked cylinder h from being lifted out of gear with the wheel on the shaft 6 when the side levers f are moved, so as to increase the distance of the spiked cylinder from the spiked sheet, I place an intermediate wheel 00 between these two wheels. The intermediate wheel is mounted on toggle-joint links 19, which keep the intermediate wheel 00 always in gear with the respective driving and driven wheels, and thus prevent disconnection. Any other suitable means might, however, be adopted to obtain the desired end-viz., that of keeping the three shafts always in drivin gconnection with each other.

The regulation of my improved feedingmachine is effected in two different modes,

At the upper end of the,

g assess each mode having its distinctive feature. In

the first place when I drive the spiked sheets 0 from the regulator-shaft m, as described, I thereby secure the evening or regulating of the feed; butin addition to this I also provide for varying the thickness of the openerlap. The means for regulating the said thickness consist in arrangements for raising and lowering the spiked cylinder h away from or closer to the spiked sheet 0. This I do by providing cams p to support the ends of the side levers f. According to the position of the cams p, which are carried on the shaft 6, the side levers, and consequently the spiked rollers h, are raised or lowered.

The shaft 6, with the cams 19, are shown in side view at Fig. 3. To turn the cams, I arrange a worm-wheelron the end of the shaft 6, which engages with a wormt on a short shaft carried in a bracket u, bolted to the side of the hopper. A hand-wheel v on the end of the short shaft is used to turn the shaft and operate the worm-gearing and so rotate the cams, whereby the side levers f are raised or lowered. The spiked cylinder h can thus be supported or set at any required distance from the spiked sheet a, and the amount of fleece passing between the sheet and the roller is regulated, so as to determine the thickness of the opener-lap. Instead of the cams and worm-gearing I might use the simpler means of set-screws 8, which also appearin Fig. 1. In thesecond instance when the spiked sheet 6 is driven at a constant velocity from anysuitable source I provide for automatic evening or regulating of the fleece, and this I do by raising and lowering the spiked cylinder It automatically through connections operated from the regulator or from a roller resting on the cottonfeed carried forward by the lattice s. The means I have designed to carry this into effect are illustrated in Figs. 4 and 5-of the drawings, Sheet 2. I extend the side levers f toward the machine being fed and connect them to a shaft or other part controlled by the regulator or by the aforesaid regulatingroller.

When'the side lovers are controlled from the regulator, I bring a rock-shaft g from the regulator, this rock-shaf t receiving its motion from the belt-fork of the regulator, soas to vibrate up and down to 'a certain extent. Upon the rock-shaft I fix a lever w, (see Fig. 5,) which is connected to a link n by a lever z, pivoted on the bridge-bracket 1. An adj ustable rod 2 connects the lever z to the crossbarf of the side levers f. It will thus be seen that the movements of the shaft q will result in moving the side levers f, and therefore raise and lower the spiked cylinder h, so that the evenness or regularity of the fleece is thereby maintained irrespective of the speed of the spiked sheet 0. The other mode of automatically governing the spiked roller h from a roller resting on the cotton-feed is shown in dotted lines in Fig. 4. I arrange a roller 3 to rest upon the cotton-feed on the lattice s. This roller is connected by an adjustable rod 4 to the cross-bar f of the side levers f, as in the former instance.

If the thickness of the cotton-feed on the lattice 3 should vary, the roller 3 rises or falls and correspondingly moves the side levers f and the spiked roller it. Thus the thickness of the fleece passing between the spiked roller h and the spiked sheet 0 is regulated by the thickness of the cotton-feed being carried by the lattice s to the scutcher or opener. The auxiliary roller 71'; and the stripper Z are also carried by the side levers f, and therefore move in unison with the spiked cylinder 7b.

The operation of my improved feeding apparatus is as follows: The cotton or other fibrous material is thrown into the hopper B or upon the lattice b, and the traveling lattice 11 carries against the spiked sheet 0, which lifts the cotton to the spiked cylinder 7t. Here the cotton is broken and opened to a certain extent by the revolving cylinder 7L, and the quantity of cotton delivered is also regulated by the adjustment of the cylinder h, as hereinbefore described. The bulk of the fiber is carried on by the spiked sheet 0 to the stripper g, but a portion is also carried around by the cylinder It. Any lumps which may adhere to the cylinder h are broken up by the smaller spiked roller 7e, and any fiber removed by the roller 70 is stripped therefrom by the stripper Z and returned to the hopper I The main stripper g acts upon both the spiked cylinder 71, and the spiked sheet 0 and strips the cotton into the chute j, down which it slides to the traveling feed-apron s, which conducts the cotton to the scutcher, opener, or other preparing machine with which my improved feed apparatus is being worked.
